Clinical predictors of lumbar provocation discography: a study of clinical predictors of lumbar provocation discography.
Discography is the only available method of directly challenging the discs for pain sensitivity. However, it is invasive, expensive and there is a debate about its clinical value. There is a need to identify clinical signs that may indicate the need for a discography examination. ⋯ History of persistent pain between acute episodes, a significant loss of extension and a subjective report of 'vulnerability' in what is termed as the 'neutral zone' had specificities of 83-92% and likelihood ratios between 2.0 and 4.1. Two combinations of variables were highly specific to positive discography, but no suitable screening test useful for ruling out positive discography was established. Three clinical variables have modest predictive power in relation to lumbar discography results and two combinations of variables were highly specific to positive discography.

The results of lumbar fusion in chronic low back pain (LBP) patients vary considerably, and there is a need for proper patient selection. Lumbosacral orthoses have been widely used to predict outcome, however, with little scientific support. The aim of the present study was to determine the value of a pantaloon cast test in selecting chronic LBP patients for lumbar fusion or conservative management. ⋯ In patients with previous spine operations the outcomes were poor and the test was of no value. From the literature and the present patient cohort, it was concluded that only in chronic LBP patients without prior spine surgery, a pantaloon cast test with substantial pain relief suggests a favorable outcome of lumbar fusion compared to conservative management. The test has no value in patients who have had previous spine surgery.

Randomized Controlled Trial Multicenter StudyEfficacy and tolerability of paracetamol/tramadol (325 mg/37.5 mg) combination treatment compared with tramadol (50 mg) monotherapy in patients with subacute low back pain: a multicenter, randomized, double-blind, parallel-group, 10-day treatment study.
In various pain studies, the single-dose combination of paracetamol/tramadol (PIT) was found to be more effective than either agent alone. PIT could provide benefit in patients with subacute low back pain (LBP). ⋯ Tramadol, alone and in combination with paracetamol, provided highly effective analgesia for these patients with subacute LSP However, the combination of PIT, which resulted in 25% less tramadol than equianalgesic daily doses of T alone, considerably reduced the incidence of AEs and improved tolerability.

A prospective cohort study with 1-year follow-up. ⋯ The incidence, especially for NSP, is much lower than from developed countries. To study prevalence, incidence and recurrence of LBP and NSP simultaneously leads to a better understanding of the natural pattern and distribution of LBP and NSP in a working population.

Background. Since 1988, spinal cord stimulation (SCS) has been used at Odense University Hospital for patients with refractory angina pectoris. The aim of our prospective study was to evaluate the long-term effects of SCS on pain, activities of daily living (ADLs), quality of life (QOL), sleep hygiene, and physical functioning for patients with angina pectoris. Methods. Before and after placement of SCS for patients with intractable angina pectoris, we performed structured telephone interviews questioning for pain relief, ADLs (Nottingham Health Profile), physical functioning (Seattle Angina Questionnaire) and sleep hygiene. ⋯ About 30% of patients discontinued treatment, the most common cause being electrode displacement and malfunction of the system. Other reasons for discontinued therapy were the evolvement of invasive treatment options such as coronary artery bypass graft and PTCA and use of such options in some patients during our prolonged observation period. Conclusion. This survey shows that SCS leads to a 70-80% improvement in pain, which, in turn, leads to improvement in QOL, whereas, physical condition and sleep pattern did not improve to the same extent.
